The interactions between slip band, deformation twins and grain boundaries in commercial purity titanium

Thesis

This thesis apply High Resolution Electron Back Scatter Diffraction (HR-EBSD) technique to a variety of microstructure features and their interactions in pure h.c.p polycrystals. By correlating high quality Kikuchi patterns with a reference pattern, the relative state and distribution of strain, stress, and geometrically necessary dislocation (GND) density can be obtained with high strain sensitivity (10^-4) and angular resolution (10 radian). This technique is com...
